CVE-2026-34164
This data is exposed to anyone with access to application logs or any Valtimo user with the admin role through the Admin UI logging module.
Does this matter?
Lower severity and a low EPSS score (0.37%). Track it; it rarely justifies an emergency change on its own.
Description
Valtimo is an open-source business process automation platform. In versions 13.0.0 through 13.21.0, the InboxHandlingService logs the full content of every incoming inbox message at INFO level. Inbox messages can contain highly sensitive information including personal data (PII), citizen identifiers (BSN), and case details. This data is exposed to anyone with access to application logs or any Valtimo user with the admin role through the Admin UI logging module. This issue has been fixed in version 13.22.0. If developers are unable to upgrade immediately, they can restrict access to application logs and adjust the log level for com.ritense.inbox to WARN or higher in their application configuration as a workaround.
